Do you not see that ships sail through the sea by the favor of Allah that He may show you of His signs? Indeed in that are signs for everyone patient and grateful. 31 When the waves engulf them like shadows [of death], they call to God, sincere [at that moment] in their faith in Him alone: but as soon as He has brought them safe ashore, only some of them take the right course. And none denies Our signs save the perfidious and ungrateful person. 32 O people, fear your Lord and dread the day when no father will avail a son, nor son his father. Truly the promise of God is true. Do not be deluded by the life of this world, and do not let the deceiver draw you away from God. 33 Indeed, Allah [alone] has knowledge of the Hour and sends down the rain and knows what is in the wombs. And no soul perceives what it will earn tomorrow, and no soul perceives in what land it will die. Indeed, Allah is Knowing and Acquainted. 34
